"*Be it kn'own that I, WILLIAM, Hams .SWETT', a citizen of the United States, residing at Berkeley, in the county of Alameda and State Of California, haveinvented certain new and useful Improvements in T- of whichfthe following is a specification.

' This invention relates 'to apparatus for producing solutions for destroying insects and refers especially to that class of solutions with insect destroying properties which are used for spraying plants.

The invention has for its-object to pro-.

vide an improved apparatus'for' preparing solutions for 'destroyinginsects, .said apparatus being constructed and arranged as hereinafterset forth and claimed.

This invention has special reference to the production of an insect destroying solution .which contains ingredients employed for spraying plants.

' Referring to the accompanying drawings -Figure 1 is a view in' elevation and partly in vertlcal 'sectlon of anapparatus constructed in accordance with thls mvention. Fig.2 is a horizontal section: on-the line XX of Fig. 1.

In carryingout the invention 'a receptacle 1 of suitabl'e'size and shape is employed which is "mounted on supports 2 and has extending through its top a pipe 3 which terminates, at a slight distance from the bottom of the receptacle land is open at its lower end and provided with, holes 4; whereby the gas may be partly broken up" as it leaves the I pipe 3. The upper end of the pipe 3 pro-' ects a short distance above the top of the receptacle land is formed withafunnel 5 frornwhic'h projects upward a combustion chamber or receptacle 6 provided withfa suitable "cover 7 having number of. vent-holes 9 The bottom of the a handle-8 and a receptaclefi'isprovided'with a grate 10.1

' Located in the pipe 3slightly abovethe top of the receptacle ljis a diaphragm 11 of reticulated material for the passage of air which serves to catch. the ashes dropping through the grate-10. and from which said ashes can be removedthrough'a door 12 in j the side of the pipe 3; Secured to the'lower end of thepipe 3 above the holes 4 and extending from the inner side-of the receptacle is a conical screen 13 whichserves to screens 14 and 15 extending from side to side in'the receptacle, the screen 15 being of finer mesh than the-screen 14. Communicating with the top of the, receptacle 1 is a pipe 16 which may be closed by a damper 16, the pipe 16 communicating with the ash pit 17 below the grate of-a stove 18 having an escape pipe 19.

The apparatus is operated as followsf: I

Tobacco being burned in the combustionchamber 6 and the drafts in the ash pit and fire box of the stove 18 being closed, a suction is created from the receptacle 1 through the pipe 19, thereby maintaining a constant flow of air and gas from the combustion'chamber 6 down through the tube 3 to the ash pit 17 of the stove 18. This flow of air maintains the combustion in the chamber passes through the liquid in the receptacle 1 the harmful ingredients of tobacco f such as nicotin enter into solution with the liquid. During warm weather when the sun is shining the apparatus may be operated by natural draft. This maybe accomplished by extending the pipe 19 to a suflicient height and at the same time painting itbla'ck, while the-apparatus is located in a cool place in the shade." By regulating the. height of'the Water. in the receptacle 1 .the apparatus may be used with any available amount of draft. When only a small quantity of the solution is to be made and it is not desired to start a fire in the stove '18 a suction pump 20 maybe employed for exhausting the air inthe receptacle 1, said pump-being mounted on the top of the latter; In conjunction with the exhaust pump 20, an air pipe 21 is employed located on the side of the receptacle 1 and provided with a cock 22 and a filling tube and funnel 23, and' argage 24. A draw off 0061: 25 is employed with the receptacle 1.

.What Icla1m is:

end terminating adjacent to the bottom of said receptacle, a combustion chamber havchamber 6 and the receptacle 1 being filled -with water, as the gas from the combustion 1. 'In a' tobacco-smoke absorption appaing an open lower end, and a grating above the same, said combustion chamber being mountedion .the upper end of said vertical pipe, and means" for causing a downward draftfrom said combustion chamber and up through the liquid containing receptacle andw above the same.

i v2. In a tobacco-smoke absorption iappatical pipe projecting through the top of-said receptacle and having its lower open end adjacent "to the bottom of said receptacle, a

* combustion chamber with a grating, and an liquid 1 containing.

open lower end mounted on the-upper end of said vertical pipe, screens located in said receptacle between said pipe and the sides of said receptacle, and means for causing a draft downward from said combustion chamber through said vertical pipe and upward in said liquid .con'

- throughcthe top of said receptacle and havtaining chamber and out of the same.

3. In a tobacco-smokeabsorption apparatus, a-liquid -containing receptacle, a vertical pipe projecting through the top of said receptacle, and open at both ends with its lower end ceptacle and having perforations in the side of said end, a cone shaped screen above said holes between said pipe andthe sides of the and horizontal screens located in.

receptacle,

said receptacle above said' cone shaped- .screen, a co bustion chamber having a lower open end with a grating mounted on the upper end of said vertical pipe, and means forcau'sing a said .combustionchamber through said verratus, a liquid adjacent to the bottom of said re-' draft downward from tical pipe, I containing chamber and out of the same.

4.111 wa tobacco-"smoke absorption appacontaining receptacle, a vertical pipe projectingjthrough the top of said receptacle, and open at both ends, with its lower open end adjacent to the bottom of said receptacle,

screens located in said re ceptacle, a reticulated diaphragm" adjacent to the upper end of said pipe, a door adjacent to said diaphragm in said pipe, a combustion chamber having a lower openend', and a grating mounted above the top of the upper end of said pipe, :1 stove, and a pipe connecting the ash pit of said stove he top of said liquid containing receptacle.

5. A tobacco-smoke absorption apparatus comprising a liquid contaimng receptacle, a vertical pipe open at each end projecting in its lower end adjacent to the bottom of sald receptacle, screens located in said receptacle, a combustion chamber with'a lower andlupward through said liquid 1 open end and a grating mounted on the top I of said vertical pipe, a filling pipe, 'and a cock 'connected-w'ith the upper end of said receptacle, and an air pump on the top of said receptacle;
